Abstract: PROCESS FOR PREPARING IMINODIACETONITRILE                 Abstract of the Disclosure Iminodiacetonitrile is prepared by a process comprising:         (a) forming an aqueous reaction mixture by admixing water, hexamethylenetetramine, formaldehyde, and HCN; and (b) forming iminodiacetonitrile by passing the aqueous reaction mixture through a continuous reaction zone while maintaining the temperature within the continuous reaction zone at 50-250°C.  The resulting iminodiacetonitrile can be recovered or it can be hydrolyzed to form an alkali metal salt of iminodiacetic acid which can be recovered or converted to iminodiacetic acid which can be recovered.    In other embodiments:   (a)  the hexamethylenetetramine solution and the formaldehyde solution can be combined before being admixed with the HCN; or (b) the formaldehyde solution and the HCN can be admixed with a stabilizing acid to form an acid stabilized aqueous solution of formaldehyde and HCN before being admixed with the hexamethylenetetramine solution in the reaction zone in which iminodiacetonitrile is formed.

Abstract: ABSTRACT OF THE DISCLOSURE         A method of assembling and preloading a joint assembly wherein a pin having a shank and a head at one end is disposed with the shank passing through aligned apertures of a plurality of workpieces to be joined.  The shank of the pin extends beyond the surface of the workpiece and is provided with an irregular surface configuration.  A deformable collar having an initially smooth surfaced internal bore is disposed about the extending shank and is snugged against the adjacent workpiece by a removably positioned means placed in abutting relationship against the free surface of the collar to lightly clamp the joint assembly together to remove free play in the joint.  The collar is radially inwardly deformed by a crimping tool so that the initially smooth surfaced internal bore of the collar is deformed to assume a configuration complementary to the irregular surface configuration of the pin shank and upon continual application of the crimping force an axial elongation of the collar and the shank of the pin is effected to provide a predetermined tension or preload on the joint assembly.  After the collar has been deformed, the means to snug the joint together initially is removed.

A bypass valve connected between the inlet pipe and the first outlet pipe and provided with a valve controlled by a pressure switch is operable to divert a portion of the hot gas flow from the inlet pipe through the bypass pipe to the exterior condenser when the rate of discharge of the gas by the compressor exceeds that which can be absorbed by the heat reclaim condenser.
